I just looked at normal-size bags of the same product i have here at home. They are 24 oz bags. For this deal, 3 x 64 = 192 oz, which is 8 normal-size bags. The 24 oz bags are $7.79 at my local grocery store, which comes out to about $62 for 8 bags. With Subscribe and Save you can get the price down to half of that on Amazon. Looks like it contains buttermilk, which may be a problem in gluten-free baking. I won't get into the details here, but the info is widely available.
